如何让搜索引擎快速确定网站的首选域How can a search enginequickly determine the preferred domain for a web siteFirst, the preferred domain is also an important point ofoperation that we should pay attention to when we do SEO. Itis directly related to the ranking of our homepage.

First, let' s see what is the preferred domain:

You may be doing domain name resolution when it should be found,we will bring WWW and without www domain name together to dowell. We can also easily understand that, which is what we wantto appear in the search engine search results, this is ourpreferred domain.

But there is also a standard explanation: the preferred domainis the domain that you want the search engine to index your pages(and sometimes also to the canonical domain) , which is thepreferred domain name for the site.

For example: Red Tao electricity supplier circle blog has twodomain names: www.ab3e.com ab3e.com, then search enginesdefault believe that the two domain names are pointing to thesame site. After the search engine is collected and displayed,it chooses one of the domains to show it to the user. Then thedomain name is called the preferred domain.

The search engine, often two domain names will appear in searchresults, which not only can affect our website ranking, but alsodistributed in the first page of the weight, because the searchengines do not knowwhich one is our main domain name extension.

Baidu seems to be quite common, basically will be the site' stwo domain names are listed in the search results.

Today, let' s talk about how to make the search engine quicklydetermine the preferred domain for the site

1, website links all use absolute address (including: insidechain, outside chain, link) , in fact is also doing URLstandardization of a process. (recommendation: how to do URLStandardizati on)?

2, if the virtual host supports 301 redirects, you can pointthe domain without WWW to the domain name with www. When buyinga host, ask whether or not you support 301 redirects. Currentlydone after 301, it seems that Baidu will still search to recordtwo domain names, but the weight of WWW will be moreconcentrated)

3, go to the search engine submission, as far as possible tosubmit the name of the domain name we want to rank.

4, do the parsing, first only resolve a domain name, and soincluded normal, and then resolve without www domain name. (abit extreme, but can effectively solve the search engine,quickly determine the preferred domain, but later orunavoidable to do 301, will not take www point to the domainname with WWW)

A black hat SEO SEO second, and we often say cheating, somefriends and even scared. In fact, many websites use black hatSEO because they don't need long rank and speed. Of course, Tao

Tao is not good at this, but there is some simple understanding.There are many kinds of websites that are like this. They needto be able to move up and down a bit for a while, and they don'tneed OK for three years or five years. As long as you can grabin front of others, OK. So today, let' s take a look at whatwebsites black hat SEO can be used for:

Last year, I was often asked to do S service websiteoptimization, they do not require long-term stability, as longas in a short period of time can row up, can row in a day. Ofcourse, this site canbe definedas illegal sites, dothis site,there must be a lot of resources in hand, and only by individualcombat, it is impossible to get up.

There are search engines to find S clothing friends all know,those sites are often changed, basically impossible to whichdomain name for a few years. As long as they can row up, butK immediately change the domain name, may be a must for severalmonths? They rely on others to open S service businesses onadvertising to profit, of course, can of course be nothingdifficult to row up profit.

Then the flow to other people' s Taobao shop to trade, andfinally by the return of gold to profit.

Last year, Baidu has been hitting Taobao sites, resulting ina large number of Taobao guest sites being K. But this does notmean that the industry has disappeared, and now there are alarge number of Taobao customers operating in the website, butthey also basically do not require long, as long as you can ina short row up OK. If you can put a popular word can be put upa short time, the profit is also very impressive, but there mustbe a technical basis, including the use of black hat SEOtechnology.
